Warriors coach Mark Jackson said Bogut was not expected to make the trip to Los Angeles for Friday night's game against the Lakers.
Bogut exited Golden State's 116-97 loss with 2:55 remaining in the first quarter. He went to the locker room for observation and did not return to the bench.
He has missed 48 of 79 games this season, most due to the ankle he broke in January 2012 before coming over in a trade that sent Monta Ellis to Milwaukee. He had microfracture surgery on the ankle in April. Thursday night was his 19th straight game played.
The Warriors already have clinched a playoff berth.
